Version 1.3.21 (in progress)
==================================
01/10/2004: cheetah (William Fulton)
The output format for both warnings and errors can be selected for
integration with your favourite IDE/editor. Editors and IDEs can usually
parse error messages and if in the appropriate format will easily take you
directly to the source of the error. The standard format is used by
default except on Windows where the Microsoft format is used by default.
These can be overridden using command line options, for example:
$ swig -python -Fstandard example.i
example.i:4: Syntax error in input.
$ swig -python -Fmicrosoft example.i
example.i(4): Syntax error in input.
01/09/2004: beazley
Fixed [ 871909 ] simple namespace problem.
This was a problem using anonymous structures in a namespace.
